Similar
in size and structure to Earth, Venus has been called Earth's twin.
These are not identical twins, however – there are radical differences
between the two worlds.
Venus is the second planet from the Sun, and Earth's closest planetary
neighbor.
Venus is the third brightest object in the sky (remember the word
sky and it does not mean universe) after the Sun and Moon.
Venus spins slowly in the opposite direction from most planets.
Venus has a thick,
toxic atmosphere filled with carbon dioxide and it’s perpetually shrouded
in thick, yellowish clouds of mostly sulfuric acid that trap heat,
causing a runaway greenhouse effect. It’s the hottest planet in our
solar system, even though Mercury is closer to the Sun. Venus has
crushing air pressure at its surface – more than 90 times that of
Earth – similar to the pressure you'd encounter a mile below the ocean
on Earth.
Venus is named for the ancient Roman goddess of love and beauty.
Most features on Venus are named for women. It’s the only planet named
after a female god.
Venus diameter at its equator = About 12,104 kilometers
Earth's diameter = Abot 12,756 kilometers
